Bi Tou had a slightly muscular build and looked like he was a strong guy. He barely had any armor as a foot soldier. He had a small beard and spiky hair.
He was very loyal to Shin, he respected and admired him. He was scared in his first war and could barely breathe, but got used to it later on. He also has a sense of humor as he pretended to be dead to annoy Shin. It is witnessed by Kyou Kai that he farts in his sleep.
When he was a kid, Bi Tou and his brother Bi Hei found a young Shin and Hyo that were quite famous in the village. Bi Hei started a fight with Shin but they were both easily defeated by Shin. Shin began calling them the thug brothers from that point forward.
Shin appointed him as a 5 Man Squad Leader in the Qin vs Zhao war. When the Hi Shin Unit attacked Hou Ken, Shin got serious injuries. The Man Goku army chased them and soon caught up quickly to the Hi Shit Unit. As they started fighting, he and his brother Bi Hei quickly hid with the unconscious Shin. They split from the rest of their unit and start running away. Knowing that the Man Goku army will find them soon due to their blood trail, Bi Hei decides that Shin's life is more important then both of his and Bi Tou's, and suggests for them to split up. Bi Hei acts as a distraction while Bi Tou carries Shin. At the end of that day, Shin wakes up while both him and Bi Tou are lying on the ground on a hill. Shin thanks Bi Tou for saving him. Bi Tou says that Shin should become a Great General and fullfill his dream, and 'dies'. Shin starts crying as Bi Tou quickly says it was just a joke, making Shin nervous. Bi Tou says that they should both relax and sleep to get ready for the next day, which Shin agrees with. However, Bi Tou dies few moments later.
He was quite enduring, since he was able to carry Shin a long time.
- [To Shin]
"Everyone put their lives on the line to protect you. Even thought it wasn't an order, they still risked themselves for you. That isn't normal. That would never happen to a normal captain, Shin. Which is why I thought to myself... If it's Shin, he can definitely become a General." (Chapter 148, page 15)
- [To Shin]
"Everyone wanted to see the same dream as you. And that's enough... Which is why, just like this, you should keep on going... ride the thoughts and wishes of all your comrades and climb your way up to a Great General of the Heavens." (Chapter 148, page 16)
